Qidam al-ʿālam is the thesis that the world, or its underlying reality, has no temporal beginning. Calling the world created is a different kind of claim: it denies that the world is independently self-sufficient or necessary in itself. Detailed arguments engage questions about beginnings, causation, and existence.
Example of reasoning: “We did not observe its beginning” does not establish “It never began.” The first is about the limits of observation; the second asserts a fact about reality.
Terms such as “eternal,” “pre-eternal,” “originated,” and “created” must be defined before the arguments can be fairly compared. Otherwise disputants may appear to disagree while talking past one another.
